Problems solved by technology

[0003] However, this will cause the heat generated by the battery module in the box to be unable to be discharged out of the box smoothly, causing the temperature inside the box to rise, thereby bringing safety hazards to the rechargeable battery pack
Secondly, because the battery module is formed by fixing multiple battery cells through welding frames, the size of the entire battery module is unstable and the weight is relatively large. Assembly brings difficulties, reduces assembly efficiency, and is not conducive to the individual replacement of battery cells, that is, the damage of one battery cell will cause the entire battery module to be unusable. Therefore, it is not conducive for maintenance personnel to quickly replace the battery module group, the maintenance cost is relatively high

Abstract

An embodiment of the present invention provides a battery pack, including at least two battery cells, a BMS control assembly, and a casing; the at least two battery cells and the BMS control assembly are arranged in the casing; each battery cell They are respectively electrically connected to the BMS control assembly; the BMS control assembly includes a protective casing and a conductive structure protruding from the protective casing, and the electronic components of the BMS control assembly are sealed in the protective casing. The battery pack provided by the embodiment of the present invention is easy to dissipate heat, and can reduce the protection level of the battery pack casing without lowering the safety level of the battery pack, reduces the difficulty of assembly, and improves production efficiency; at the same time, it is convenient for later maintenance of the battery pack and Replacement and maintenance of battery cells.

Description

【Technical Field】 [0001] The present invention relates to the technical field of batteries, in particular to a battery pack. 【Background technique】 [0002] Electric vehicles are vehicles that use rechargeable battery packs to drive wheels. They are favored by low- and middle-income groups due to their low price, convenience, and environmental protection. The rechargeable battery pack generally includes a battery cell module, a BMS control module, and a box housing the battery cell module and the BMS control module. In order to ensure the safety of the battery cell module and the BMS control module, the structural strength of the box used to encapsulate the battery cell module and the BMS control module is very high, so as to achieve the purpose of strengthening the protection level. [0003] However, this will cause the heat generated by the battery cell module in the box to be unable to be smoothly discharged outside the box, which will cause the temperature inside the box to ri...
